DVB-S/S2 to DVB-T TTX-410C R81617 transmodulator is used for reception of DVB-S/S2 (8PSK/QPSK) signals, selection of desired channels from a transponder, and retransmission of them in COFDM format in chosen channel in VHF/UHF frequency range. Built-in CI interface for conditional access modules enables the transmodulator to operate with scrambled services. In multiplexing mode, one panel receives a whole multiplex (up to 10 or so channels) and converts it to DVB-T multiplex with up to 5 services (max 31 PIDs) with max throughput of 31.66 Mbps. When a higher throughput is required, the system should be equipped with additional TDX-410C R81617 module(s). The output DVB-T COFDM multiplex is usually distributed to users by a passive network composed of RF splitters/taps. Such a solution is especially convenient in modern hotel TV systems distributing a variety of satellite channels, including HD broadcasts.

The TDX-410C R81617 panel has CI (Common Interface) slot that in the case of receiving encrypted programs must be equipped with suitable conditional access module (CAM) with dedicated smart card.

A great advantage of the Terra device is easy integration with other components:

IPTV streamers for management and distribution of satellite, terrestrial and cable DVB channels within Ethernet (LAN) networks based on twisted-pair cabling,
optical transmitters for transmission TV programming via optical links,
other receiving and signal processing devices (broadband and channel amplifiers, analog and digital modulators).

DIPOL offers the following transmodulators of DVB-S/S2 (8PSK, QPSK) signals:

List of services with additional information

Set of ttx410C R81615 and tdx410C R81617 transmodulators used in an SMATV system. For the reception of pay-TV channels it is necessary to install suitable conditional access module.

Notice: The transmodulator is compatible only with CI CAM modules (no support for CI+).
